  • Anisotropic heat conductive composition and molded product thereof
    Patent number: 9487690
    Abstract: The present invention relates to an anisotropic heat conductive composition including flake graphite particles and a resin composition for the particles to be dispersed therein. When the particles have a basal plane, a maximum diameter a in a direction of the basal plane, and a thickness c perpendicular to the basal plane, a/c is 30 or more on average, and a content of the particles is more than 40 mass % and 90 mass % or less. Since the composition includes the particles having a particular shape, when it is formed into a sheet, an anisotropic heat conductive path can be efficiently created therein. Thus, the present invention can provide a molded product in sheet form, suited to have therein a heat conductive path capable of dispersing heat from a high temperature region to a low temperature region.
